摘要/Abstract

摘要： 为了改善柴油机喷雾空间分布，提高缸内空气利用率，加强燃烧室内的气流运动，提出了带双ω燃烧室的燃烧系统，并在ZS1100M型柴油机上进行了初步性能试验。研究结果表明：双ω燃烧室的几何形状对柴油机燃烧系统的油耗与排放性能有较大的影响。在额定工况下，57型燃烧室方案的油耗与碳烟排放最低；65型燃烧室方案的NO_x排放与原机相比基本不变，油耗却降低了2.2%，碳烟排放降低了8.3%. 在额定转速下，65型燃烧室的油嘴突出高度在2.6 mm时油耗与碳烟排放性能最优。在转速1 500 r/min下，采用双排喷孔的各方案在中小负荷时油耗均比采用单排喷孔的原机方案要低；适当增加上排喷孔数，减小双ω燃烧室的喉口直径能进一步降低油耗。

Abstract: In order to improve the spatial distribution of injection spray and the mixture formation quality for diesel engines, a combustion system with double ω combustion chamber is proposed to strengthen the motion of airflow in the combustion chamber. The preliminary performance test of combustion system with double ω combustion chamber is made on ZS1100M diesel engine. The results show that the geometrical shape of double ω combustion chamber has a great influence on the fuel consumption and emission performance of combustion system for diesel engine. The fuel consumption and soot emission of 57-type combustion chamber are the lowest under the rated operating condition. Compared with the original combustion chamber, the fuel consumption and soot emission of 65-type double ω combustion chamber are reduced by 2.2% and 8.3%, respectively, at rated operating condition while the NO_x emission remains basically unchanged. 65-type combustion chamber with 2.6 mm nozzle height possesses the optimal fuel consumption and soot emission performance at the rated rotating speed. At the rotating speed of 1 500 r/min, the double ω combustion chamber with double-row nozzle holes shows better fuel consumption rate under the small and medium loads. The proper increment of the upper-row nozzle holes and a decrease in throat diameter could further reduce the fuel consumption rate.
